ATTORNEYS United States Patent 3,400,232 MULTIPLE FUNCTION CIRCUITCONTROLLER AND CIRCUIT Charles J. Mathey, Dearborn, Mich., assignor toFord Motor Company, Dearborn, Mich., a corporation of Delaware FiledSept. 30, 1966, Ser. No. 583,249 13 Claims. (Cl. 200-18) ABSTRACT OF THEDISCLOSURE This circuit controller serves efiiciently as a master switchfor the power windows of a motor vehicle. Primary switches for operatingthe window motors are located around the inside periphery of a switchhousing and secondary switches for reversing the polarity at the primaryswitches are located on the floor of the housing. A wand projecting fromthe housing pivots a cross shaped member to move arms into touch withindividual primary switches or any two adjacent primary switches,thereby actuating motors controlled by the switches to raise theassociated windows. Depressing a knob on the wand simultaneously withthe above pivoting actuates the secondary switches to reverse thepolarity at the primary switches and thereby lower the appropriatewindow. Cams on a member rotatable by rotation of the knob in onedirection actuate all primary switches concomitantly to raise all thewindows and, with depression of the knob described above, to lower allthe windows. A pin actuated by rotation of the knob in the oppositedirection acts on one of the secondary switches to disconnect theprimary switches from the power source, thereby preventing accidentalactuation of the master switch and, with the disclosed circuitry, alsopreventing unauthorized actuation of switches mounted for use by theoccupant of the seat near each window.

This invention provides a circuit controller capable of performing avariety of parallel and series switching functions individually andconcomitantly and a circuit for utilizing the controller. One importantuse of the controller is as a master switch for the power windows of anautomobile.

Most master switches for power windows used commercially in the pastwere merely an aggregation of separate switches arranged in a singlepanel. The panel necessarily was located where it could be operatedconveniently by the driver of the vehicle. Because of its bulk, thepanel usually was mounted in the drivers door, where it was inaccessibleby other front seat passengers. In vehicles having two front seatsseparated by a console, the panel occasionally was mounted in theconsole where it was accessible by both front seat passengers, but inthis location the size of the panel preempted space useful for otherequipment such as radios, storage compartments, and safety padding.

The circuit controller of this invention combines the switchespreviously placed in the bulky panel in a compact housing where a singlewand actuates each switch individually or several combinations ofswitches concomitantly, the term concomitantly being used herein to meanthat the switches are actuated by an integral movement but are notnecessarily actuated simultaneously. In addition, other switchingoperations not provided previously are incorporated in the controller.The controller comprises a housing having a plurality of primaryswitches, each having a switch pole movable to complete and break acircuit mounted therein. A cross-shaped member having arms adapted tomove the switch poles is mounted in the 3,400,232 Patented Sept. 3, 1968housing. A wand projects from the housing and pivots so movement thereoftoward a primary switch moves an arm of the cross-shaped member toactuate that switch.

In refined versions of the controller the primary switches areelectrically in parallel with each other and are mounted at the insideperiphery of the housing. A typical housing is square shaped andcontains four primary switches, one along each wall. Each primary switchis associated with a motor for operating one of the four side windows ofa typical vehicle. If desired, a five sided housing containing fiveprimary switches where the fifth switch is associated with a motor foractuating the tailgate of a station wagon or other housing shapes andnumbers of primary switches can be provided.

Secondary switches electrically in series with the primary switches canbe mounted at the floor of the housing and the wand can be designed soaxial movement thereof actuates the secondary switches. The secondaryswitches reverse the polarity at the primary switches. Pivotal movementof the wand concomitant with the axial movement actuates a primaryswitch. Thus, with minimum activity, a window is selected and raised orlowered.

Cam means can be provided so rotation of a knob on the wand cam-s thecross-shaped member downward to actuate concomitantly all of the primaryswitches. In addition, a second cam means can be provided so rotation ofthe knob in the opposite direction acts on the secondary switches todisconnect the controller from the power source. With the circuitry alsoprovided by this invention this disconnection will prevent windowoperation by the individual switches mounted proximately to each window.

The drawings show a controller of this invention having a four sidedhousing with four primary switches that is designed to actuate motorscontrolling the power windows of a vehicle. In the drawings, FIGURE 1 isan exploded view showing the housing and the switches in the left columnand the wand in the right column;

FIGURE 2 is a bottom view of the housing showing the terminals used toconnect the switch into an electrical circuit;

'FIGURE 5 is an exploded view of an alternate wand construction in whichrotation of a knob of the wand in one direction actuates all primaryswitches concomitantly and rotation in the other direction prevents thecontroller and any switches located proximate to the window fromoperating the window motors; and

FIGURE 6 is a diagram of a circuit using the controller and proximatelylocated switches to operate power window motors.

Referring primarily to FIGURES l, 2 and 3, the housing for the circuitcontroller of this invention is indicated generally by the numeral 10and comprises four upstanding walls 12, 14, 16 and 18 mounted squarelyon a floor 20. Floor 20 has a raised block 22, 24 and 26 in each corner(the fourth block is not shown in the drawings because of the cutout).The blocks are inward slightly from walls 12, 14, 16 and 18 so a narrowspace exists between each block and the walls. Each block has a holeextending through floor 20.

Raised lands 30, 32, 34 and 36 are located on floor 20 along each wall.Like the raised blocks, the raised lands are inward from the walls so anarrow space (e.g., numeral 37 in FIGURE 1) exists therebetween. Eachland has a high step 30a, 32a and 34a (36a is not shown because of thecutout) at one end and a low step 30b, 32b and 36b (34b is not shownbecause of the cutout) at the other end. Each step also has a holeextending through floor 20, and a slot (not shown) for a space-typeterminal is formed in floor between e ach high step and the adjacentblock.

A square opening 38 is cut in the middle of floor 20. Opening 38 isstepped to form an opening 40 at the bottom side of floor 20 that islarger than opening .38 at the top side. Threaded holes 42 and 44 areformed in floor 20 on each side of opening 38. .Adjacent land 32, holes46 and 48 are cut into floor 20 and on the opposite side of opening 38,four additional holes, only two numbered 50 and 52 of which are shownbecause of the cutout portion of the drawings, are located in a lineparallel to land 36. Ordinarily, housing 10 with the above constructionfeatures is molded as a unit fromany of the electrically insulatingplastics.

Referring to the portion of FIGURE 1 below housing 10, a. rocker block54 having two parallel vertical slots 56 and 58 therein and a horizontalhole 60 intersecting both slots is adapted to fit loosely in opening40..Slots 56 and 58 are subtended by opening 38, and the sides of block54 are tapered slightly inward at the bottom. A I

case 62 loosely surrounds block 54 and is fastened to housing 10 byscrews 64 and 66 threaded into holes 42 and 44, respectively. Block 54and case 62 also are made of plastic. Compression spring 68 seats incase 62 and urges block 54 upward into opening 40.

The secondary switch means is indicated generally in FIGURE 1 by thenumeral 70. FIGURES 2 and 3 also show some of the parts of the secondaryswitch means, although these parts are designated therein by theirrespective numbers. Secondary switch means 70 comprises two switch poles72 and 74 mounted on floor 20 by rivets 76 and 78 passing through holes46 and 48, respectively. Rivets '76 and 78 emerge at the bottom of floor20 (see FIGURE 2) where rivet 76 fastens flat lug 80 and rivet 78fastens L-shaped lug 82 to housing 10. L-shaped lug 82 has a spade-typeterminal 84 projecting therefrom.

Electrical contacts 86 and 88 are located at the other end of poles 72and 74, respectively. Mounted in hole 52 and its associated hole (notshown) in floor 20 below contacts 86 and 88 are contacts 90 and 92,respectively. Stepped mounting members 94 and 96 are attached to floor20 by rivets 98 and 100 passing through hole 50 and its associated hole(not shown) and position contacts 102 and 104 above contacts 86 and 88,respectively. Poles 72 and 74 are formed so contacts 86 and 88 normallyare in touch with contacts 102 and 104 but are movable by a slightdownward force out of touch therewith and into touch with contacts 90and 92.

Rivet 100 and the rivet connected to contact 90 fasten stepped lug 106shown in FIGURE 2 to the bottom of housing 10. Similarly, rivet 98 andthe rivet connected to contact 92 fasten C-shaped lug 108 to the bottomof housing 10. Lugs 106 and 108 carry respective projecting spade-typeterminals 110 and 112. v

The primary switch means are indicated generally in FIGURE 1 by thenumeral 113. As with secondary switch means 70, parts of the primaryswitch means shown in FIGURES 2 and 3 are designated therein by theirrespective numbers. Primary switch means 113 comprise a lower buss bar114 fitting into the space (e.g., numeral 37) along the walls andextending around three sides and part of the fourth side of housing 10.Buss bar 114 has four tabs 116, 118, and 122 that rest onlower steps30b, 32b, etc. Contacts 117, 119, 121 and 123 have connected rivetspassing through holes in tabs 116, 118, 120 and 122 and the holes insteps 30b, 3211, etc., respectively. The rivet connected to contact 117anchors in lug 30 on the bottom side of floor 20 while the rivets ofcontacts 119 through 123 anchor only in floor 20.

Four L-shaped terminals 124, 126, 128 and 130 seat respectively onhigher steps 30a, 32a, etc., with their terminal portions passingthrough the slots in floor 20v between higher step 30a and block 22,higher step 32a and block 24, etc. Note the emergence of the terminalsat the bottom of housing 10 in FIGURE 2.

i poles 132, 134,

. Q Z3 I h g 136 and 138 are fastened by rivets 140,142,144 and 146 toterminals 124, 126, 128 and 130, respectively, and to floor 20 so thepoles lie above lands 30, 32, 34 and 36. The opposite ends of poles 132through 138 have contacts 148, 150, 152 and 154 thereon that arepositioned above c'o'ntacts 117, 119, 121 and 123, respectively; I

. Stepped mounting members 156, 158, and 162 seat on blocks 24, 26, theblock not shown, and block 22 to position contacts 164, 166,168 andabove contacts 148, 150, 152 and 154, respectively. An upper buss bar172 has tabs 173, 174,175 and 176 seating on the lower step of mountingmembers 156 through 162, respectively. Rivets 177, 178, 179 and passthrough tabs 173 through 176, members 156 through 162 and through floor20 to fasten buss bar 172 and the stepped mounting members in place.Rivet 178 anchors in lug 82 at the bottom of floor '20 (see FIGURE 2),while rivets 177, 179 and 180 simply anchor-in floor 20.

Mounting members 156 through 162 position respective contacts1-64through 170 above respective contacts 148 through 154, and poles 132through 138 are formed so contacts 148 through 154' normally touchcontacts 164 through 170 but are' movable to touch contacts 117 through123 instead. Each of elements 72 through 180 is made of an electricallyconducting material.

In FIGURE 1, a wand assembly for the controller is indicated generallyby the numeral 181. The heart of wand assembly 181 is the cross-shapedmember indicated generally by the numeral 182. Cross-shaped member 182is made of a plastic disc 184 having four arms 186; 188, 190 and 192extending at right angles from its periphery. Arms 186 through 192 havedownwardly extending blocks located at their ends.

Below disc'184, two parallel legs 202 and 204 project downward for ashort distance. Legs 202 and 204 are designed to fit into slots 56 and58 in rocker block 54. Holes that will line up with hole 60in block 54are formed in legs 202 and 204; and a pin 206 passes through the holesto maintain assembly of member 182 and rocker block 54.

A semicircular stop 208 is mounted on top of disc 184 and a cylindricalshank 210. projects axially upward from disc 184. Shank 210 contains apassage 212 extending axially therethrough and through disc 184. Aprojection 214 having a hole therein is attached to the periphery ofdisc 184 between arms 188 and 190. Cross-shaped mem: ber 182 -withelements 184 through 214 is made of an electrically insulating materialsuch as one of the many plastics and usually is formed by molding.

A pin216 isslidable in the hole in projection 214 and is spring loadedby a spring 218 to an upward position. Slidable in passage 212 is a rod220 having a head 222 at its lower,end ...Rod 220 is long enough toproject for a short distance from the upper end of shank 210,

A plastic actuating block 224 is mounted slidably between legs 202 and204. In the assembledlposition, block 224 is located just above poles 72and 74. of secondary switch means 70. Downward movement of rod 220 movesblock, 224 which in turn moves poles 72 and 74 so contacts86 and 88 moveout of touch with contacts 102 and 104 and into touch with contacts 90and 92, respectively. When downward force on rod 220 is released, theresilience inpoles 72 and 74 moves block 224 upward and returnscontacts, 86 and 88 to their rest position where they again touchcontacts 102 and 104. g

'A carnming member 226 is mounted rotatably on the outer diameter of.sha nk210. Member226 has a disc 228 at its lower end and asquare-shaped portion 229 extending above the-disc. The bottom of disc228 has inclined surfaces 230and 232 extending away from each other andrunning into'fiat surfaces'234 and 236, respectively.

Pin 216 locates between inclined surfaces 230 and 232 and is cammeddownward by sliding on the inclined'surfaces when member 226 is rotatedin either direction. Rotating member 226 until pin 216 is riding on flatsurface 234 or 236 produces a static condition in which pin 216 is heldin its downward position. When members 182 and 226 are assembled inhousing 10, pin 216 in its downward position moves pole 74 to anintermediate position out of touch with contacts 92 and 104.

- The wand assembly is topped by a knob 238. A squareshaped opening 240extends a short distance into knob 238 from the bottom thereof. Aboveopening 240 is a circular opening 242 extending a short distance furtherinto knob 238 and above opening 242 is a smaller circular opening 244extending still further into knob 238. A threaded radial passage 246opens on opening 244 and the outside of knob 238 and a set screw 248 ismounted threadably therein.

Opening 240 receives square-shaped portion 229 of member 226. Similarly,shank 210 fits into opening 242 and the upper tip of rod 220 fits intoopening 244 where it is secured by tightening set screw 248. A taperedcompressive spring 250 seats at its larger end on the shoulder betweenopenings 240 and 242 and'bears on the top of square-shaped portion 229.When assembled, a short space exists between the top of portion 229 andthe shoulder between openings 240 and242, and between the top of shank210 and the shoulder between openings-242 and 244.

Triangular-shaped blocks 251 and 252 shown in FIG- URE 3 are bonded inopposing upper corners of the square formed by walls 12 through 18. Acover plate 254 shown in FIGURE 4 then is mounted on top of housing byappropriate threaded fasteners (not shown) passing through openings inplate 254 and threading into holes in blocks 251 and 252. Plate 254rests on top of disc 228 as shown in FIGURE 4.

General mechanical operation of the circuit controller takes place inthe following manner. Wand assembly 181 is capable of pivoting throughthe action of rocker block 54. Pivotal movement toward any one of polesnumbered 132 through 138 brings the block of appropriate arm 186 through192 into contact with the pole and thereby moves the pole out of touchwith appropriate contacts 164 through 170 and into touch withappropriate contacts 117 through 123. Pivotal movement toward anintermediate position between any two adjacent poles 132 through 138brings both appropriate adjacent arms 186 through 192 into contact withthe poles to actuate concomitantly the adjacent primary switch means.When the pivoting force on the wand assembly is removed, spring 68 movesthe wand assembly back to a neutral upright position.

Pressing knob 238 downward slides rod 220 in crossshaped member 182,moving block 224 into poles 72 and 74 and thereby moving contacts 86 and88 out of-touch with contacts 102 and 104 and into touch' with contacts90 and 92, respectively. Then pivoting wand assembly 181 as described inthe preceding paragraph concomitantly actuates one or two primary switchmeans.

FIGURE 5 shows an alternate construction of members 182 and 184 thatprovide means for actuating all primary switch means concomitantly. Inthis alternate construction, stop 208 on the top of disc 184 is replacedby four evenly spaced inclined members 256, 258 and 260, the fourthinclined member being hidden behind shank 210. These inclined membershave their inclined surfaces running in the same circumferentialdirection. Cam carrying member 226 then has four inclined members 2.62,264, 266 and 268 mounted on the bottom of disc 228. The inclinedsurfaces of members 262 through 268 slide on the inclined surfaces ofmembers 256, 258, etc.

Radially outward of members 262 through 268 is a single inclined member270 having'its inclined surface running in a direction opposite to thatof members 262 through 268. The inclined'surface of member 270 ispositioned to contact pin 216.- Other parts in the wand assembly areunchanged.

With the alternate construction, rotating knob 238 counterclockwiserotates member 226' so members 262 through 268 act through members 256,258, etc., to cam cross-shaped member 182 downward so arms 186- through192 actuate all primary switch means concomitantly. Rotating knob 238clockwise acts through member 270 to cam pin 216 into pole 74 asdescribed above. In this alternate construction, suificient clearancemust be provided, of course, in case 62 for slight lateral movement ofblock 54.

In describing the circuit in FIGURE 6, the numerals used to designateparts in the controller also will designate the portions of the circuitthose parts represent. The portion of the circuit contained in thecircuit controller is enclosed by dotted line 272. A direct currentsource such as a battery 274 has its positive terminal 276 connected toterminal and its negative terminal 278 connected to terminal 112. Withincontroller 272 stepped lug 106 transmits the positive potential tocontacts 90 and 104 and C-shaped lug 108 transmits the negativepotential to contacts 92 and 102. Pole 72 normally touches contact 102and pole 74 normally touches contact 104 but these arms are movable tocontacts 90 and 92 concomitantiy by block 224 represented in FIGURE 6 bya dotted line. Pin 216 is positioned above pole 74 and is capable ofmoving that pole to the intermediate position represented by the dottedline just below the pole.

Lug 80 connects pole 72 with lower buss bar 114 and contact 117. Lug 82connects pole 74 with upper buss bar 172 and terminal 84. Buss bar 114connects with contacts 119, 121 and 123 and buss bar 172 connects withcontacts 164, 166, 168 and 17-0. Poles 132, 134, 136 and 38 of primaryswitch means normally touch contacts 164, 166, 168 and 170,respectively, but are movable to contacts 117, 119, 121, and 123,respectively. Terminals 124, 126, 128 and 130 connect with poles 132,134, 136 and 138, respectively.

Electric motors 280, 290, 300 and 310 have their output shafts connectedto appropriate gearing for operating the windows of a vehicle. Forpurposes of illustration, motor 280 will be treated as if it operatesthe left front window, motor 290 operates the right front window, motor300 operates the right rear window, and motor 310 operates the left rearWindow.

The poles 281 and 282 of two single pole double throw switches areconnected to the leads of motor 280. Pole 281 normally touches a contact283 but can be thrown to a contact 284, and pole 282 normally touches acontact 285 but can be thrown to a contact 286. Similarly, poles 291 and292 of two single pole double throw switches are connected to the leadsof motor 290; Pole 291 normally touches contact 293 but can be thrown tocontact 294, and pole 292 normally touches contact 295 but can be thrownto touch contact 296. Similar poles 301, 302, 311 and 312 and contacts303 through 306 and 313 through 316 are associated withmotors 300 and310.

Contact 285 is connected to a terminal 287 that connects with terminal124 of the circuit controller. Similarly, contact 295 is connected to aterminal 297 that connects with terminal 126, contact 305 is connectedto terminal 307 that connects with terminal 128, and contact 315 isconnected to a terminal 317 that connects with terminal 130. A buss line320 connects contacts 283, 293, 303 and 313 with a terminal 322 thatconnects with terminal 84. Another buss line 324 connects contacts 284,286, 294, 296, 304, 306 and 314 and 316 through an external conductor326 to negative terminal 278 of battery 274.

With each switch pole, including those in controller 272, in its normalposition, poles 281 and 282 apply a positive potential to both sides ofmotor 280 so no motor operation takes place. Note that the normalposition of the switch poles always equalizes the potential across themotors instead of simply disconnecting one side of the motor; thisprovides dynamic motor braking and improves motor life.

Assume that poles 281 and 232 are in their normal positions and pole 132is moved to contact 117. This applies negative battery potential to pole282. With a positive potential at pole 281 and a negative potential atpole 282, motor 280* operates to raise the left front window. With pole132 still in touch with contact 117, depressing block 224 to move poles72 and 74 into touch with contacts 90 and 92, respectively, reverses thepotential at .poles 281 and 282, thereby reversing the operation ofmotor 280 to lower the left front window. Similar operation of poles134, 136 and 138 results in similar operation of motors 2.90, 300 and310.

Assume now that the poles in circuit controller 272 are in their normalposition and the occupant of the seat next to the left rear window(motor 310') desires to change the position of his window. Again, withpoles 311 and 312 in normal positions, a positive potential is appliedto both sides of motor 310. Moving pole 312 to contact 316, however,applies a negative potential to pole 312 and motor 310 operates to raisethe left rear window. Releasing pole 312 so it returns to its normalposition in touch with contact 315 and moving pole 311 to contact 314applies a positive potential to pole 312 and a negative potential topole 311 so motor 310 operates to lower the window. Similar operations,of course, can be effected by the occupants of seats adjacent each ofthe other windows. Note that the in- !dividual switches containing poles281, 282, 291 and 292 for Operating the left and right front windows,respectively, can be eliminated when circuit controller 272 isaccessible by both front seat passengers.

Depressing pin 216 moves pole 74 to an intermediate position where itdoes not touch either contact 92 or 104. This cuts off the potential atcontacts 164, 166, 168 and 170 in circuit controller 272 and contacts283, 293, 303 and 313 in the individual switches. Moving pole 311 tocontact 314 applies a negative potential to pole 311 but does notproduce motor operation because of the incomplete circuit from pole 312to the other side of battery 274. A similar situation exists if pole 312is moved to contact 316. Thus motor 310 cannot be operated by theindividual switches located at the window or, for that matter, "bypivotal movement of Wand assembly 181. Through the use of pin 216, thevehicle driver easily prevents undesired operation of the windows.

Thus, this invention provides a circuit controller capable of actuatinga plurality of primary switches in parallel with each other individuallyor concomitantly. The controller also can contain secondary switches inseries with the primary switches and can actuate the secondary switchesindividually or concomitantly with the primary switches. An electricalcircuit using the circuit controller as the remotely located mastercontroller for operating a plurality of individual motors, each motorhaving individual switches proximately located, also is provided by thisinvention. Obvious safety advantages flow from the means in thecontroller and the circuit for preventing undesired operation of themotors by the proximately located switches.
